250 yards per spool. I know it is overkill but I never have to respool my tip ups with new line.We use the bright orange or yellow 30# flyline backing.The bright color allows us to see which direction the fish are running easier.
I have 3 sets of tip ups : Set 1 Polars set up for deep water with 250 yards on each .Set 2 polars with smaller 100 yard spools for shallow water fishing.I also have a set of Heritage tip ups for fishing in deep snow,these also have 100 yards of line on them.
Hopefully I will have a bunch of videos this winter.One of the new goodies I got is a 30gb hard drive video camera .Now I can shoot and upload video directly to my pc and the internet.
